Embodiment tetra-:
The embodiment of the present invention four is to support the wireless communication module 1 of GSM/TD-SCDMA and to support the wireless communication module 2 of GSM/TD-LTE as example in embodiment bis-, in conjunction with Fig. 2, the scheme of the embodiment of the present invention three is described, in the present embodiment four, describe as an example of starting up of terminal network selection scene, terminal gravity treatment scene, terminal handoff scenario example respectively.
1, starting up of terminal network selection scene.
Under start scene, wireless communication module 1 and wireless communication module 2 can be selected resident network according to predefined mode.For example: for the predefined mode of wireless communication module 1 is: only select TD-SCDMA, only select GSM, preferably TD-SCDMA, preferred GSM or automatically select etc.; For the predefined mode of wireless communication module 1 is: preferably TD-LTE.
After starting up of terminal, if terminal environment of living in does not have the TD-LTE network coverage, but there are GSM and the TD-SCDMA network coverage, and because the priority of wireless communication module 1 is higher than the priority of wireless communication module 2, therefore, wireless communication module 2 need to according to the resident network of wireless communication module 1 and frequency range select self can be resident frequency range.
As shown in Figure 5, the resident process to corresponding network and frequency range of application processor control wireless communication module 1 and wireless communication module 2 comprises the following steps:
Step 201: wireless communication module 2 is initiated the resident request of the resident frequency range 3 to GSM to application processor.
Step 202: application processor judges whether to receive request that wireless communication module 1 sends and reside in the resident request of GSM, if receive, execution step 203; Otherwise, execution step 206.
The object of this step is to judge whether wireless communication module 1 needs to reside in GSM, because the priority of wireless communication module 1 is higher than the priority of wireless communication module 2, therefore, if wireless communication module 1 need to reside in GSM, the preferential resident frequency range to needing of wireless communication module 1.
Step 203: application processor judges that wireless communication module 1 asks whether resident frequency range is frequency range 3, if so, performs step 204; Otherwise, execution step 206.
Step 204: the resident frequency range 3 to GSM of application processor control wireless communication module 1.
The detailed process of this step is:
First, application processor sends the information of frequency range 3 to base band submodule 1;
Then, the frequency range receiving 3 information are sent to radio frequency chip 1 by base band submodule 1.
Finally, the interface of switching mode receiving filter and the interface conducting of switching power amplifier of radio frequency chip 1 and radio-frequency front-end device Mid Frequency 3.
Step 205: resident other frequency range to GSM of application processor control wireless communication module 2, and finish.
The detailed process of this step is:
First, application processor to base band submodule 2 send can resident frequency range 2,5,8 information;
Then, base band submodule 2 is selected the information of the frequency range 2,5,8 receiving according to predefined criterion, determines the resident frequency range of the current needs of GSM in base band submodule 2, and this band information is sent to radio frequency chip 2; If base band submodule 2 finds not have under current state frequency range can be resident time, do not send any band information to radio frequency chip 2.
Then, radio frequency chip 2 is opened the reception/sendaisle of its correspondence according to the band information receiving from base band submodule 2, and the interface of the switching mode receiving filter corresponding with this frequency range and the interface conducting of switching power amplifier.For example: if base band submodule 2 requires the resident frequency range 8 to GSM, the receive path of radio frequency chip 2 Mid Frequencies 8 and transmission channel respectively with the interface of switching mode receiving filter and the interface conducting of switching power amplifier of frequency range 8; If baseband chip 2 does not send any band information to radio frequency chip 2, radio frequency chip 2 can not with the interface conducting of the interface of the switching mode receiving filter of frequency range 2,5,8 and switching power amplifier, now wireless communication module 2 can not be resident to GSM.
Step 206: the resident frequency range 3 to GSM network of application processor control wireless communication module 2.
2, terminal gravity treatment scene.
Under terminal gravity treatment scene, as long as there is the TD-LTE network coverage terminal region, wireless communication module 2 will reselect to TD-LTE network, and wireless communication module 1 is still according to the undefined mode network selection of starting up of terminal network selection scene.
Under terminal gravity treatment scene, have two kinds of possible situations to occur, the first situation is that wireless communication module 1 also needs to reside in GSM in the time of wireless communication module 2 resident GSM; The second situation is that wireless communication module 1 does not need to reside in GSM before wireless communication module 2 resides in the frequency range 3 of GSM, but after wireless communication module 2 resides in the frequency range 3 of GSM, wireless communication module 1 needs again to reside in GSM.Be illustrated respectively for both of these case:
The first situation:
(1) if wireless communication module 1 resides in TD-SCDMA network after starting up of terminal, wireless communication module 2 resides in TD-LTE network, when fast mobile terminal is when only having the region of the GSM network coverage, wireless communication module 1 is selected frequency range resident in GSM by having precedence over wireless communication module 2.
As shown in Figure 6, the resident process to corresponding network and frequency range of application processor control wireless communication module 1 and wireless communication module 2 comprises the following steps:
Step 301: wireless communication module 2 is initiated the resident request of the resident frequency range 3 to GSM to application processor.
Step 302: application processor judges whether the interface conducting of switching mode receiving filter and the switching power amplifier of GSM, if so, performs step 303; Otherwise, execution step 305.
In the structure shown in Fig. 3, wireless communication module 1 is connected with all switching mode receiving filters of GSM and the interface of switching power amplifier, if wireless communication module 1 resides under a certain frequency range of GSM, radio frequency chip 1 by with the interface conducting of switching mode receiving filter and the switching power amplifier of this frequency range; If wireless communication module 1 does not reside in GSM, all switching mode receiving filters of GSM and the interface of switching power amplifier all should be in the states of conducting not.
Step 303: whether application processor judges the interface conducting of the switching power amplifier of switching mode filter G3 and frequency range 3, if so, performs step 304; Otherwise, execution step 305.
The object of this step is to judge whether wireless communication module 1 resides in frequency range 3, if wireless communication module 1 has resided in frequency range 3, wireless communication module 2 can only reside in other frequency range; If wireless communication module 1 does not reside in frequency range 3, represent that wireless communication module 1 does not need to reside in frequency range 3, wireless communication module 2 can reside in frequency range 3.
Step 304: resident other frequency range to GSM of application processor control wireless communication module 2.
Step 305: the resident frequency range 3 to GSM network of application processor control wireless communication module 2.
